Yield until animation is over?

Question

Hi there! I'm editing this question for the very last time, to better depict you with my problem, what I'd wanted to do and how I managed to solve it.

The problem I had was very specific: I wanted to create a Progress Bar and let the player press a button to stop its refilling; everytime the refilling would have been stopped, an animation was to be played.

But, since I'm a very flexible demander, I thought I could get along with slightly different results... So my pretension was just to have different animation played depending on which time the progress bar was stopped, and the best possible outcome for me was to be told how to synchronize perfectly those two things ( Progress Bar and Animations).

So far my question received no answer but a week ago I finally managed to solve this issue by myself, that's why I thought I could share with you my own solution.

I'll post that as an answer.

Again, my trouble was ( and I suspect I can safely say that still is) to time the refill of the Progress Bar so that the next refill would wait for the current animation to be finished before starting to fill once more.

Answer 1

So, here is my code so far. I'm posting this as an answer because it gets the job done as far as I'm concerned, of course this is far from saying it's the best solution. Plus I'm a newbie programmer so my code is not fully optimized either.

Instead of leaving this question unanswered, I'm putting my two cents in it.

Two more things to notice: first one, this thing is not perfectly synchronized but it works anyway; second one, the countdown thing I made was just a work out and is not intended to function outside the editor... it's probably the most confused part of the code and I suggest you to ignore it.

 using UnityEngine;
 using UnityEditor;
 using System.Collections;
 
 public class FinalProgressBar : MonoBehaviour {
     
     /* WHAT IS THIS?
      * This script handles the behaviours of the Progress Bar... what progress bar? well, I've drawn one with
      * photoshop but you probably can't see it from where you are.
      * The purpouse was to make an interactive Progress Bar Minigame similar to the first of Kirby's Fun Pak
      * ( Megaton Punch)
      * 
      * I'm rewriting it ( 3rd time) so that it can be more performant and accurate.
      * It may turn out messy as it was before, who knows!
      * 
      * AS FAR AS I'M CONCERNED, THIS SCRIPT WORKS THE WAY I INTENDED, I'M HAPPY :D
      * credits? okay: this thing was written by esitoniatteso@gmail.com ( I've stolen some methods hither and thither of course)
      * 
      * write me if you want, I can be social!
      * 
      * P.S.: of course this thing lacks both a score and a countdown mechanic, and right now is intended to be a
      *          standalone scene ( no menus, no quit, no gameover, just THIS scene here).

         wrong.enabled=false;
         plus.enabled=false;

         three.enabled=false;
         s1g2=false;
         anim.SetBool("s1g1",false);
         anim.SetBool("s1g2",false);
 
         //print ("Reset All done");
     }
     void Cow(){
         //Cow is a function that says Unity what to do next, after you press the button
         // to make it work properly those ifs need multiple conditions but I don't know why, they should be implicit.
         if(s1g1 & tempo<=total/2){
             anim.SetTrigger("s1g1");
         }
         if(s1g2 & tempo>total/2){
             anim.SetTrigger("s1g2");
         }
     }
 }

If I have to say what I was doing wrong in the beginning, I'd say that was pretending to manage animations through code... once I wrapped my head around the new features of the Animator I started to comply with the right path, and SetTrigger used properly helped a lot.

Yield until animation is over?
